i been working (slowly) on a web browser and i gotten teh get command to be pretty good but the only problem is that on some servers they inculde in the file your downloading another copy of the header and/or insert gaps into the file
and on alot of servers (like these fourms) insert odd numbers inbeween chunks or have the chunks in a diffrent order then you see normaly
i find it hard to find a solid html file (or any file inculing images sounds and moives) that isn't mixed up or has anything added to it to mess up the content lenght that i am using to verify if the file is done downloading
so i trying to figure out WHY are they add such things to webservers...
http get and werid servers...

Re: http get and werid servers...
In the chunked transfer encoding the server is allowed to send entity headers at the end of each chunk. You need to ignore these and look for a blank line which indicates the end of the trailing headers.Dreglor wrote:servers they inculde in the file your downloading another copy of the header
That sounds like it could be the end of the trailers.and/or insert gaps into the file
And they are not just the lengths of the chunks?and on alot of servers (like these fourms) insert odd numbers inbeween chunks
If you are only downloading one file at a time, then it should come in in the correct chunk order. There doesn't appear to be any indicator in HTTP/1.1 for what chunk comes from whatever position.or have the chunks in a diffrent order then you see normaly
Have you got an example of the pages you are downloading? I mean the raw data as you download it (with all transfer encodings present), not the HTML file that is being transferred.i find it hard to find a solid html file (or any file inculing images sounds and moives) that isn't mixed up or has anything added to it to mess up the content lenght that i am using to verify if the file is done downloading

If you paint your butt blue and glue the hole shut you just themed your ass but lost the functionality.
(WinXPhSP3 PB5.20b14)
(WinXPhSP3 PB5.20b14)
well these headers are at the top and theres only 1 of them :/In the chunked transfer encoding the server is allowed to send entity headers at the end of each chunk. You need to ignore these and look for a blank line which indicates the end of the trailing headers.
no theses are huge like 20-30 lines of blank linesThat sounds like it could be the end of the trailers.
and they apper for a halfway into the file :/
they could be but i don't understand why couldn't they generate the file then find the final lenght...And they are not just the lengths of the chunks?
heres a exmple that is the most soild, but has an extra header and the gap
heres the file it big sorry :/
and this is not raw (the program removed the server header thats all)

ORBITER is a free flight simulator that goes beyond
the confines of Earth's atmosphere. Launch the Space Shuttle from Kennedy
Space Center to deploy a satellite, rendezvous with the International Space
Station or take the futuristic
Delta-glider for a tour through the solar system - the choice is yours.<br>
But make no mistake - ORBITER is not a space
shooter. The emphasis is firmly on realism, and the learning curve can
be steep. Be prepared to invest some time and effort to brush up on your
orbital mechanics background. A good starting point is JPL's
<a href="http://www.jpl.nasa.gov/basics/">Space

base of the <a href="http://orbit.m6.net/v2/boardtalk.asp">Orbiter

<b>December 17, 2003: <font color="#33FF33">Orbiter Patch 031217</font></b>
<p>In time to celebrate 100 years of powered flight (and 3+ years of Orbiter) I have released a new patch which fixes a number of recently reported bugs and adds some new features, including cloud shadows on planetary surfaces. Get your copy from one of the download mirrors. (If you already have the 031105 version installed, please download the patch, not the full version!)
<p>For more details, check the <a href="change.html">Change Log</a>.
<p><b>November 6, 2003: New release 031105</b>
<p>It has been a while in the making, but the latest ORBITER version has finally been released. Here are a few of the highlights:
<p>A completely re-worked atmospheric flight model provides more realism during atmospheric ascents and descents. Spacecraft can now define (and animate) aerodynamic control surfaces, so Shuttle landings are now a lot more realistic.
<p>Support for particle systems for more realistic engine exhaust and reentry rendering.
<p>Higher planetary texture resolutions: Orbiter now supports "resolution level 9" with an effective equatorial resolution of 16384 x 8192 pixels! A tile manager tool bundled with Orbiter allows to apply high resolution textures selectively.
<p>Space Shuttle Atlantis can now re-capture objects, so complex missions involving deployment and collection of satellites can be designed.
<p>New models for the International Space Station (by Andrew Farnaby), Space Shuttle Atlantis (by Don Gallagher) including External Tank and Solid Rocket Boosters (by Damir Gulesich), models for the HST (by David Sundstrom) and LDEF satellite (by Don Gallagher), and a new version of the DeltaGlider with animated control surfaces (by Roger Long). Improved surface textures for both the Moon (by Jens Meyer) and Venus (by Jim Williams).
<p>New MFD modes: Duncan Sharpe's TransX for calculating complex interplanetary missions is now bundled with Orbiter, together with a new Horizontal Situation Indicator to assist with surface navigation and instrument landings.
<p>New ground-based camera modes, and the ability to save and recall multiple camera settings.
<p>A more detailed list of new features can be found in the <a href="change.html">Change Log</a>.

Get your copy from one of the download mirrors. (If you already have the 031105 version installed, please download the patch, not the full version!)

<p><b>November 6, 2003: New release 031105</b>
<p>It has been a while in the making, but the latest ORBITER version has finally been released. Here are a few of the highl ights:
<p>A completely re-worked atmospheric flight model provides more realism during atmospheric ascents and descents. Spacecraft can now define (and animate) aerodynamic control surfaces, so Shuttle landings are now a lot more realistic.
<p>Support for particle systems for more realistic engine exhaust and reentry rendering.
<p>Higher planetary texture resolutions: Orbiter now supports "resolution level 9" with an effective equatorial resolution of 16384 x 8192 pixels! A tile manager tool bundled with Orbiter allows to apply high resolution textures selectively.
<p>Space Shuttle Atlantis can now re-capture objects, so complex missions involving deployment and collection of satellites can be designed.
<p>New models for the International Space Station (by Andrew Farnaby), Space Shuttle Atlantis (by Don Gallagher) including External Tank and Solid Rocket Boosters (by Damir Gulesich), models for the HST (by David Sundstrom) and LDEF satellite (by Don Gallagher), and a new version of the DeltaGlider with animated control surfaces (by Roger Long). Improved surface textures for both the Moon (by Jens Meyer) and Venus (by Jim Williams).
<p>New MFD modes: Duncan Sharpe's TransX for calculating complex interplanetary missions is now bundled with Orbiter, together with a new Horizontal Situation Indicator to assist with surface navigation and instrument landings.
<p>New ground-based camera modes, and the ability to save and recall multiple camera settings.
<p>A more detailed list of new features can be found in the <a href="change.html">Change Log</a>.

the only thing i can explain these gaps is that don't try to find the end of the chunk i just write the whole memory buffer which at the time i was thinking it would be nothing and it wouldn't be a problem because it was writing nothing
this a bit odd if thats the case but it doesn't always happen with all of the sites i go to...

I just tried the same server as you (I think - www.medphys.ucl.ac.uk/~martins/orbit/orbit.html) with some HTTP code I wrote a while ago and I did not have any problems with gaps, chunks being out of order or the end of the file being cut off.
So I can only guess that there is some bug in your code, probably where you are getting the network events and extracting the data from the buffer. Are you sure you are completely clearing the buffer after you have finished processing a chunk and you are not writing extra spaces or something to your output file?

If you haven't already done so, your best bet might be to go to http://www.w3c.org which gives the standards for HTTP/HTML, which includes things like compacting sequential whitespace into one space.
If the page is dynamic then the script that generated it can leave whitespace (blank-line/newline) gaps.
Eg in ASP:
will leave a blank line where the script was, and lots of script snippets will leave lots of blank lines:
Which, if all conditions fail, leaves a chunk of blanks because the newline at the end of each closing tag is sent, being outside of the tag.
As far as I know content chunks should arrive at the client in the correct order - the next chunk isn't sent until the last one is acknowledged - but don't quote me on this, check w3c.

well i got the gap problem fixed 
but the content lenght is still being messed up
i try to test my program on alot of web sites so i won't post every website source i get
i have the content-lenght as a when-to-stop (by using lof() instuction) and it reads the content lenght right becasue i checked sevral times
so for an example (these are real world numbers) the site had 73892 as the lenght and when it stop sending (not using the content-lenght but a time out to finds the end) the program got was 87589 and the very end (the </html> text)was still missing
so this make me wonder if the content-lenght is only reading chr(13) for a new line and not chr(13) and chr(10) this makes me wonder if i should do some testing about this

The content length is just the number of bytes in the data you get sent. It has no special considerations for line endings or any other things which might be in the data.
What have you used as your network code when recieving the data?
